Is it possible to add a tag to AWS AMI created with Packer containing name of filtered source_ami?

Question

I am building AWS AMI with Packer. The source image is defined by filter source_ami_filter and the source block looks like

source "amazon-ebs" "test-image" {
  ami_name      = "Some AMI Name"
  instance_type = "t2.micro"
  region        = "eu-central-1"
  source_ami_filter {
    filters = {
      name                = "ubuntu/images/hvm-ssd/ubuntu-focal-20.04-amd64-server-*"
      root-device-type    = "ebs"
      virtualization-type = "hvm"
    }
    most_recent = true
    owners      = ["099720109477"]
  }
  tags = {
//    source_ami_name = ...  # how to get it?
  }
  ssh_username = "ubuntu"
}

How to get the name of the used source AMI from canonical?

There are some shared information variables, for instance, SourceAMIName.

That means you can get your source AMI name and use it as a tag by doing this:

source_ami_name = "{{ .SourceAMIName }}"
